Wood substructures
Seasoned wood or laminated wood parts can also be used for the substructure . The applicable national regulations regarding wood preservation must be observed .
Wood substructure components are generally as follows :
• Lathing ( cross lathing )
• Anchors
• Load-bearing lathing
• Cladding / wood materials
• Fasteners
When cladding with exposed joints is to be installed , vertical load-bearing lathing with joint tapes or joint profiles with sealing lips or anticapillary rails are preferable ( e . g . EPDM fluted tapes ); simple , unprofiled sheet metal strips are generally unsuitable . Joint tapes or profiles positioned behind the cladding must be fixed to prevent slipping . It is recommended that horizontal profiles are interrupted at the joints in the cladding sections . Vertical profiles can be uninterrupted .
Composite substructures
Composite substructures are a combination of metal , fiber-reinforced plastics and / or wood .
The composite substructure may consist of the following components :
• Brackets made from metal or fiber-reinforced plastics or combinations of these materials
• Stand-off bolts or distance pieces
• Thermal separators / isolators
• Anchor components
• Load-bearing profiles ( L- , T- , Z- , Ω-profiles , or similar )
• Fasteners
• Load-bearing lathing
• Cladding / wood materials
During installation , the regulations or building codes applicable to metal as well as wood must be observed .
